  Term Definition  
   
  FARAD the base unit of capacitance - equal to the capacitance of a capacitor having an equal and opposite charge of 1 coulomb on each plate and a potential difference of 1 volt between the plates (Abbreviation - F). The Farad is a very large value, and is more commonly referred to as the pico-Farad (pF, 1 x 10-12 Farad), nano-Farad (nF, 1 x 10-9 Farad), micro-Farad (uF, 1 x 10-6 Farad), and (less common) milli-Farad (mF, 1 x 10-3 Farad)  
       
  FET (FIELD-EFFECT TRANSISTOR) either a Junction FET (JFET) or a Metal Oxide Semiconductor FET (MOSFET). It is a three-terminal semiconductor that acts either as an amplifier or digital switch. One of the major characteristics of a FET is that is has an extremely high input resistance and therefore, has no loading on previous circuitry.  
       
  FILTER a circuit which is frequency dependent. The "pass band" is the range of frequencies allowed through, and the "stop band" is that range of frequencies which are blocked  
       
  FILTERING a process used to remove or accentuate specific frequencies or frequency ranges of a signal  
       
  FLIP-CHIP An integrated circuit which is designed to electrically and mechanically interconnect by means of an appropriate number of bumps and is intended for facedown mounting.  
       
  FOREIGN MATERIAL Any material that is foreign to the microcircuit or package, or any non-foreign material that is displaced from its original or intended position within the microcircuit package.  
       
  FORWARD RECOVERY TIME The length of time required for a diode in its reverse biased (OFF) state to recover to a stabilized ON state after a digital forward bias voltage is applied. If this time is 50 nanoseconds or less, the diode is applicable for use in computers and/or high-speed logic circuits.  
       
  FREQUENCY (f) The number of cycles per second of an AC wave measured in hertz (Hz).  
       
  FULL-WAVE RECTIFIER A configuration of either two or four diodes that acts to change AC to
full-wave DC The two-diode configuration is used in conjunction with a
center-tapped secondary of a transformer. The four diode configuration is used
when no center-tap exists at the transformer secondary and is called a BRIDGE
RECTIFIER.
 
       
  FUNCTIONAL CIRCUIT ELEMENTS Diodes, transistors, crossunders, capacitors, and resistors  
       
  FUNDAMENTAL FREQUENCY The lowest frequency of a complex AC waveshape represented by a single sine
wave.
 
       
  FUSE A short strip of metal having extremely low resistance and functioning as a protective device in a circuit. A fuse will melt when its rated current is exceeded, thereby opening the circuit.
